问题描述
大家好，
首先让我说我知道网上可能有数百个帖子提到asp和CR。我找了大约一个星期试图无济于事。如果你有一个你认为会有帮助的网页，我会很高兴看到它，但我一遍又一遍地谷歌这个主题。
我正在开发一个asp / C＃项目，它将获取任何水晶报告并将其显示在网页上，该部分非常简单。在这个项目中，我正在寻找简单的东西，可以在任何类型的浏览器或操作系统上连续几天/几周运行。我正在使用CR XIR2，asp.net 4.0和VS2010。我的项目将显示报告并刷新数据并报告设定的时间段。我的项目中没有数据集。该报告直接连接到SQL服务器并提取数据。我已经在asp页面上使用一些javascript进行了自动页面刷新，但是我无法自动化下一页显示。我希望每两分钟左右轮换一次页面，每10分钟左右刷新整个报告。这是我的asp页面：
Hello all,
First let me say I know that there are probably hundreds of postings on the net that refer to asp and CR. I have looked for about a week trying things to no avail. If you have a web page that you think will help I would be very happy to check it out, but I have google''d this subject over and over again.
I am working on a asp/C# project that will take any crystal report and display it on a web page, that part is simple enough. In this project I am looking for simplicity, something that will run possible for days/weeks on end on any type of browser or OS. I am using CR XIR2, asp.net 4.0 and VS2010. My project will display a report and refresh the data and report on a set time period. I do not have a dataset in my project. The report connects directly to the SQL server and pulls the data. I have gotten the automated page refresh working with some javascript on the asp page, but I am having trouble automating the next page display. I am looking to rotate through the pages every two minutes or so and refresh the entire report every 10 mins or so. Here is my asp page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register TagPrefix="CR" Namespace="CrystalDecisions.Web" Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function timeClick() {
var t = setTimeout("clickButton()", 180000);
}
function clickButton() {
var button = document.getElementById('RefreshButton');
button.click();
timeClick();
}
</script>
<script type="text/C#" runat="server">
public void CommandBtn_Click(object sender, CommandEventArgs e)
{
CrystalReportViewer1.RefreshReport();
}
</script>
</head>
<body>
<script type="text/javascript">
window.onload = timeClick;
</script>
<form id="form1" runat="server">
<div style="display: none;">
<asp:Button ID="RefreshButton" runat="server" onCommand="CommandBtn_Click" />
</div>
<div>
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="True"
Height="1039px" ReportSourceID="CrystalReportSource1" Width="901px" DisplayStatusbar="False"
HasDrilldownTabs="False" HasToggleGroupTreeButton="False"
HasToggleParameterPanelButton="False" ToolPanelView="None" />
<CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
<Report FileName="CrystalReport1.rpt">
</Report>
</CR:CrystalReportSource>
</div>
</form>
</body>
</html>
这里是我的C＃代码：
And here is my C# code behind:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Web;
public partial class _Default : System.Web.UI.Page
{
private ReportDocument rpt;
private void Page_Init(object sender, EventArgs e)
{
ConfigureCrystalReports();
}
protected void Page_Load(object sender, EventArgs e)
{
}
private void ConfigureCrystalReports()
{
rpt = new ReportDocument();
string reportPath = Server.MapPath("CrystalReport1.rpt");
rpt.Load(reportPath);
ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.DatabaseName = "******";
connectionInfo.UserID = "*****";
connectionInfo.Password = "*****";
SetDBLogonForReport(connectionInfo, rpt);
CrystalReportViewer1.ReportSource = rpt;
}
private void SetDBLogonForReport(ConnectionInfo connectionInfo, ReportDocument reportDocument)
{
Tables tables = reportDocument.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table table in tables)
{
TableLogOnInfo tableLogonInfo = table.LogOnInfo;
tableLogonInfo.ConnectionInfo = connectionInfo;
table.ApplyLogOnInfo(tableLogonInfo);
}
}
}
我遗漏了我尝试过的许多不同的方法。我希望有人可以提供帮助......先谢谢。
I have left out the many different approaches I have attempted. I hope someone can help.... Thanks in advance.

function nextPg_timeClick() {
var i = setTimeout("nextPg_Click()", 1800);
}
function nextPg_Click() {
var button1 = document.getElementById('nextPg');
button1.click();
nextPg_timeClick();
}
</script>
